Laing DDC (Swiftech MCP350/355) Names & Info

[Signal64]

I have a Corsair Nautilus 500 which uses a Laing DDC-1TP.

A couple of questions:

1. Is the noise level pretty much the same (running at the same volts) with all of the DDC pumps?

I'd like to replace it with a quieter version if possible.

2. It's mounted upside down in the external case. Is the noise level or wear and tear affected more when it's mounted that way?

Here's some pics of the external unit from a review:

The author speculates on question #2 but didn't confirm what Laing might have said.

Unfortunatly it doesn't look like I could add any of the tank mods as it's pretty tightly installed there.

1. from looking at the pics, you can see the label on the pump which reads: DDC-1TP this is the 10W version of the pump. i use the same one, but with a different top. i have also modded my pump to switch it to the 18W version. from hearing at this two configurations i would say the 18W is noticeable loader, but its not that bad. as you already have the 10W version installed, the only way to reduce noise would be a different top. but as you said, you are already out of space ...

the mounting position in the nautilus looks not recommended by laing, see the red rectangle:
